Prolonging WSN lifetime using a new scheme for Sink moving based on Artificial Fish Swarm Algorithm

In this paper, we investigate the problem of energy in Wireless sensor networks. The sensors maintain their autonomy from their batteries. These networks have a limited capacity in terms of energy mostly at the communication process which could significantly reduce the network lifetime. In order to prolong the network lifetime, by maintaining its performance, we propose a novel algorithm based on Artificial Fish Swarm Algorithm (AFSA) behaviors for sink moving in WSN. Simulation results indicate the efficiency of the proposed scheme in terms of increasing the network lifetime and giving the best rate of the delivered packets.
